Add Benny Feilhaber to the list of American stars for whom injury concerns are clouding World Cup prospects as the AGF Aarhus midfielder is now currently in Brazil to see an expert about cartilage damage in his ankle.

Feilhaber suffered the injury in training last Monday and was at first thought to have a sprain. But, as AGF chief physiotherapist Jens Bo Vestergaard Jørgensen stated last week, following an initial MRI, the injury appears to be more severe.

The club revealed that the former UCLA standout is visiting a doctor in his native Brazil with whom he has previously done rehabilitation for a 2008 knee injury.

"The physician agrees that Benny - as we have previously announced - has suffered a cartilage injury in the ankle and that it was right to use a splint on it," AGF press officer Christian Haarsløv told YA. "Benny has had his ankle MRI scanned again, and we expect to have the final results of this study early next week."

The ex-Derby County man has not been included on Bob Bradley's roster for the upcoming friendly against the Netherlands in Amsterdam. There was some thought that he might be able to return in time for the restart to the Danish Superliga season, but Haarslov was quick to dispel that notion.

"Benny will definitely not be ready for the FC Copenhagen match," he added.

AGF entered the Superliga's winter break in sixth place, 10 points out of a spot in Europe.

No definitive timeline for Feilhaber's recovery will be available until after the tests in Brazil are complete.
